While I loved seeing a map system in the game, I do have some thoughts/suggestions to it in terms of gameplay:
1) I shouldn't have to wait for Guybrush to run all the way to the location, this gets tedious especially once you've been to the same places over and over (double clicking to "teleport" you there would be great)
2) I should be able to access the map from EVERYWHERE. For example, since I can choose to get to the Dock once in map-mode, why can't I open the map from there as well?
And one last *petty* note - I would love it if the map would be in 2d. There's just a terrific vintage quality to it you can't deny :)
Hope Telltale guys are listening, you guys did an outstanding work on this game.
